Participants get initially $2000
They take a card from 1 of 4 decks.Two are bad decks.
Skin Conductance is recorded and averaged separately for the trials in which the subject choose a card from good decks vs trials where subject choose a card from the bad decks
Subjects take more often from good decks while thinking they are just guessing, they learn the good decks. (IMPLICIT LEARNING)
Before the subjects explicitly formulate the difference between the decks of cards, their body already ‘knows’. This is indicated by larger skin conductance before taking from a bad deck.(SOMATIC MARKER)
There is criticism on the experiments and the interpretation. Nonetheless Intuition seem to be driven by past information.

How do we measure presentiment:
But wait a moment.......
There are winning and loosing cards in all the decks!
So: Do not average SC over bad en good decks but over the winning and loosing cards within the decks!

From Wikipedia, the free encyclopedia:
The Novikovself-consistencyprinciple, alsoknown as the Novikovself-consistencyconjecture, is a principledevelopedbyRussianphysicistIgor Dmitriyevich Novikov in the mid-1980s to solve the problem of paradoxes in time travel, which is theoreticallypermitted in certainsolutions of general relativity (solutionscontainingwhat are known as closed timelike curves). Statedsimply, the Novikovconsistencyprincipleassertsthatifaneventexiststhatwouldgiverise to a paradox, or to any "change" to the past whatsoever, then the probability of thatevent is zero. In short, itsaysthatit'simpossible to createtime paradoxes
Parapsychology develops into para-physics with ‘retrocausality’ as key topic. Experimental paradigms are from psychology.
Physics does not exclude ‘advanced’ effects
Retrocausality implies restrictions in replication.
Sequential replication might intrinsically becoming more and more difficult.
